The relapse rate for drug addiction can vary depending on several factors, including the type of drug, the severity of the addiction, the duration of the addiction, and the effectiveness of the treatment. However, according to the National Institute on Drug Abuse (NIDA), the relapse rates for drug addiction are estimated to be around 40 to 60 percent. It’s important to note that relapse does not necessarily mean failure, and it’s possible to recover from addiction even after relapse. It’s also important to seek ongoing support and care after completing treatment, such as attending support groups, participating in counseling, and utilizing other resources to help maintain sobriety and reduce the risk of relapse.
